für Druckmaschinenfor printing machines
Die Erfindung betrifft eine Rakelhalterung zur Verwendung inbesondere in Druckmaschinen zum Drucken oder Übertragen von Fluiden, Pasten oder Farben.The invention relates to a doctor blade holder for use in particular in printing machines for printing or transferring fluids, pastes or inks.
Ziel der Erfindung ist es, ein rasches Auswechseln der verbrauchten Rakel zu erreichen, um mitunter lange Maschinenstillstandzeiten zu vermeiden. Bei Verwendung der am Markt üblichen Rakelhaltern wird die Rakel durch Verschraubung gequetscht. Die Rakel verformt sich mit der Folge von Qualitätseinbußen beim Druck. Ein weiterer Aspekt ist, dass beim Verschrauben feinste Metallpartikel entstehen, die sich in Pasten und Farben als Verschmutzung ablagern und, inbesondere bei Einsätzen in Reinräumen zu Ausschussproduktionen führen. In noch stärkerem Maße gilt dies vor allem für Ablagerungen von Pasten und Farben im Umfeld der Schraubenköpfe.The aim of the invention is to enable the used squeegee to be replaced quickly in order to avoid long machine downtimes. When using the squeegee holders commonly available on the market, the squeegee is squeezed by screwing. The squeegee becomes deformed, resulting in a loss of quality during printing. Another aspect is that screwing creates the finest metal particles that are deposited in pastes and inks as contamination and lead to rejects, particularly when used in clean rooms. This applies even more to deposits of pastes and inks in the area around the screw heads.
Die am Markt befindlichen, bekannten Rakelhalter erfüllen diese Anforderungen nicht.The known squeegee holders available on the market do not meet these requirements.
Somit ist es Aufgabe der Erfindung,Therefore, the object of the invention is
- die Fixierung des Rakels zu bewerkstelligen, ohne die Rakelkante durch "Quetschen" zu verformen,- to fix the squeegee without deforming the squeegee edge by "squeezing" it,
- die Halterung so zu konzipieren, dass das Umrüsten/das Wechseln des Rakels vereinfacht und beschleunigt wird und- to design the holder in such a way that the conversion/changing of the squeegee is simplified and accelerated and
- mit der Gestaltung der Oberfläche der Rakelhalterung Verschmutzungsrisiken konsequent auszuschließen.- to consistently exclude the risk of contamination by designing the surface of the squeegee holder.

Die Erfindung wird nachstehend anhand zwei Skizzen erläutert.The invention is explained below using two sketches.
Das Gehäuse der Rakelhalterung besteht aus einem rechteckigen Metallprofil, das je nach Einsatzerfordernis entweder aus einem Stück geformt, oder aus zwei Halterungshälften besteht, die mit Stiften zusammengehalten und mit der übrigen Oberfläche plan geschliffen und poliert werden.The housing of the squeegee holder consists of a rectangular metal profile which, depending on the application requirements, is either formed from one piece or consists of two holder halves which are held together with pins and ground and polished flat with the remaining surface.
An Stelle des Verschraubens zur Fixierung des Rakels (1) drückt eine der Geometrie des Rakels angepaßte Zentrierleiste (2) in Richtung senkrecht zu der zu bedruckenden Oberfläche (3), mindestens teilflächig auf den Rakel und presst diesen in Richtung der zu bedruckenden Oberfläche, ohne die Rakelkante zu verformen.Instead of screwing to fix the squeegee (1), a centering bar (2) adapted to the geometry of the squeegee presses in a direction perpendicular to the surface to be printed (3), at least partially on the squeegee and presses it in the direction of the surface to be printed, without deforming the squeegee edge.
Das Öffnen der Halterung zum Einlegen und Entnehmen des Rakels wird mittels einer Einschubößhung (4) bewerkstelligt. Eine durch Daumendruck zu bedienende Drückvorrichtung (5), die sich Oberhalb der Einschuböffhung in Richtung zur Druckmaschine befindet, wird die Zentrierleiste wieder in die Ausgangsposition gebracht und gibt den Rakel frei; in Sekundeschnelle durchfuhrbar. Der Zentrierleiste liegt maschinenseitig eine Druckleiste (6) gegenüber, die mehrere Vertiefungen aufweist, in denen Nadelköpfe (7) von Nadellagern angebracht sind.The holder is opened to insert and remove the squeegee using an insertion opening (4). A thumb-operated pressing device (5) located above the insertion opening in the direction of the printing machine returns the centering bar to its original position and releases the squeegee; this can be done in a matter of seconds. Opposite the centering bar on the machine side is a pressure bar (6) which has several recesses in which needle heads (7) of needle bearings are mounted.
Damit ist diese Form der Rakelhalterung beispielsweise für die Produktion von Multilayern oder Keramik-Tapes in idealer Weise geeignet. Je nachdem, wie sich die Konsistenz der zu verdruckenden Paste darstellt und wie tief Rakel und Rakelhalterung in diese Paste eingetaucht werden, können die Seiten der Rakelhalterung ganz bzw. teilweise mit Metallplatten verschlossen werden, um ein Eindringen von Pasten oder Farben in die Halterung zu vermeiden.This type of squeegee holder is therefore ideal for the production of multilayers or ceramic tapes, for example. Depending on the consistency of the paste to be printed and how deeply the squeegee and squeegee holder are immersed in this paste, the sides of the squeegee holder can be completely or partially closed with metal plates to prevent pastes or colors from penetrating the holder.
Die Vorteile dieser Rakelhalterung gegenüber Halterungen, die dem heutigen Stand der Technik entsprechen, liegen im erheblich schnelleren Handling, in der verbesserten Druckqualität (keine Verformung des Rakels) und in der Vermeidung von Ausschußproduktion durch Verschmutzung.The advantages of this squeegee holder compared to holders that correspond to the current state of the art are the significantly faster handling, the improved print quality (no deformation of the squeegee) and the avoidance of rejects due to contamination.
